HEATING VESSELS OR CHAMBERS BY STEAM.

SPECIFICATION forming part of Letters Patent No. 417.189, dated December 10, 18819.

' Application filed April 22,1889. Serial No. 308,087; [No model.) Patented in England April 18, 1885, N 1

.To aZZ whom it may concern.-

Be it known that I, CHARLES JONES, builder,

a subject of the Queen of Great Britain, lately residing at 2 Lower IVhitecross Street, in the 5 city of London, but now residing at Maude Villa, Chelmsford Road, East IVoodford, En gland, have invented certain new and useful Improvements in Apparatus used when Heating Vessels or Chambers by Steam-Heated Z Jackets, (for which I have obtained Letters Patent in Great Britain, No. 4,834, dated April 18, 1885,) of which the following is a specification.

This invention has for its object to enable ivessels or'chambers to be effectually heated by means of steam supplied to jackets surrounding such vessels without subjecting the vessels or jackets to any material pressure, while at the same time insuring that a slight pressure of steam shall always be maintained within the jackets and avoiding the blowing off of steam from them freely into the open air.

For supplying the steam to the steam-jackets I employ, by preference, a steam-boiler heated by the combustion of gas supplied to gas-burners, the apparatus for supplying gas to the burners being so constructed that when the pressure in the boiler rises to the re- 3c qnired maximum the supply of gas to the .burners is for the most part out off.

When a series of vessels, each surrounded by its own steamjacket, is to be heated by steam from a steam-boiler, I lead off from the steam-pipe which passes from the boiler a.

branch pipe into each steam-jacket, and I carry up this branch pipe to some distance above the bottom of the steam-jacket, so that no water produced by the condensation of o steam in the jacket may pass back into it. Upon each branch pipe I also provide a cock, by which the amount of steam admitted to the jacket can be controlled. From the bottom of each steam-jacket I lead a pipe down- Ward. The lower end of this pipe I contract and make'to dip down nearly to the bottom of a small spherical or other formed vessel, into which water produced by the condensation of steam running off from the steamjacket may be collected. This vessel I form with a tubular neck extending upward from it and surrounding the upper end of the-contracted portion of the descending pipe. From this tubular neck a branch pipe is led off, through which all water flowing into the con.- densed-water-collecting vessel may iiowaway freely after this vessel is filled. The column of water between the bottom of the pipe which leads from the steam-jacket and this overflow-pipe insures a slight pressure of steam in each steam-jacket and prevents steam from blowing oif freely from them.

The drawings annexed show an apparatus arranged as above described.

Figure 1 shows a small steam-boiler and a steam-pipe led off from it for conveying steam to the steam-jackets of two vessels which are to be heated. Any desired number of vessels might be heated from the same steampipe. The vessels shown in the drawings are such as are commonly used for holding a supply of boiling water, which can be drawn off as required by a tap. Fig. 2 is a section of the valve for supplying gas to the boiler, and Fig. 3 shows the way in which the vessel F is formed and secured to the end of one of the outlet-pipes E.

A is the steam-boiler, made as described in the before-mentioned application for patent. It is heated by the combustion of gas sup- 8o plied to burners O by a pipe I. Gas is admitted to this pipe from a chamber R, to which gas is supplied by a pipe S. The admission of gas from the chamber to the pipe P is controlled by a valve T, normally held open bya spring U. The stem of the valve is carried up through the top of the chamber and coupled to afiexible diaphgram V,which closes the bottom of a chamber WV, put in communication with the interior of the boiler by a pipe X. In this way, when the pressure in the boiler rises sufficiently for the pressure on the top of the diaphragm to overcome the spring U, the valve T closes and cuts off the full supply of gas to the burners. Sufficient gas to keep the flame at the burners from being entirely extinguished is, however, then allowed to pass to the burners through the small orifice Y. \Vhen the pressure in the boiler falls, the valve T opens and a full supply of gas again passes to the burners.

B is a steam-pipe leading from the top of the boiler. I v

O C are branch steam-pipes led up into the steam-jackets of the two vessels D. On each of these branch pipes is a tap D by which the amount of steam admitted to each jacket may be regulated.

E E are pipes led off from the bottom of each steam-jacket and made to dip into a spherical or other vessel F, from the top of which is an overflow, to which a waste-pipe is secured, through which excess of steam may blow off and water produced by the condensation of steam in the steam-jacket flow away.

The way in which I form the vessel F and secure it to the end of one of the outlet-pipes E is shown at Fig. 3. G is a screw unionpiece to screw on to the end of the pipes E. H is a ring-union securing a piece I to the piece G. The lower end of the piece I has screwed into it part of the enlarged upper end of a pipe J Onto the other part of this enlarged end is screwed the end of a neck K, which projects up from the spherical vessel F. This neck has a branch pipe M standing out from it, to which the Wastepipe N is coupled. The condensed water collecting in the vessel F seals its end, and, as above explained, maintains always a slight pressure of steam in the steam-jackets of the vessels D, while at the same time it acts as a safetyvalve, insuring that these vessels shall never be subjected to excessive pressure.

The same arrangement of apparatus may be used when heating all kinds of vessels or chambers with steam-heated jackets.

What I claim is- 1. The combination, substantially as hereinbefore set forth, of the boiler A, the steamjacketed vessels D, pipes extending from the boiler up into the vessels D, the vessels F below the steam-jacketed vessels D, pipes E, extending from the bottom of the steam-jackets of the vessels D downwardly, screw-plugs G, secured to the lower end of the pipes E and removably secured to pipes connected with the vessels F, the pipes J, rising from the lower portion of the vessels F, and the pipes N, connected with the vessels F below the upper ends of the pipes J and having a common discharge-pipe.

2. The combination, substantially as hereinbefore set forth, of the steam-jacketed vessel D, the globular vessel F, formed integrally with a neck K,havinga branch pipe Mat one side,'the short pipe-section I, joining the upper end of the neck K, the pipe J, rising from the lower end of the globular vessel F and having an enlarged screw-threaded end connecting the pipe-section I and the, neck K, and the ring H, connecting the screw unionpiece with the pipe-section I.
